The first time the unit is booted up, it will present the Display Mode screen. Every time after this, it will present the previously used display mode.


To give you the opportunity to use the unit without connecting it to a power source, we have an optional battery (RLACS290) available for the Performance Box Touch. 

When the battery is installed, you can press and hold the Power button on the battery for a few seconds to turn the unit on or off. 

If you plug the power cable into the unit when the battery is already attached to the unit, the unit will turn on automatically. 

The battery will provide at least 6 hours of battery life. However, you can increase the battery life to a maximum of 9 hours by using the minimum brightness settings.

PB Touch Battery Front.png
When Performance Box Touch is on, and the battery is installed, you will see a Battery Status Indicator displayed in the top right corner of the screen. This will provide you with a visual representation of the remaining battery charge. The indicator is split into 10 bars, each representing a 10% charge. When the battery is charging, you will see a charging symbol appear over the battery symbol. PB Touch Battery Icon.png
If the battery has less than a 10% charge left, you will see a warning screen appear on the display, which will be displayed for 10 seconds. To cancel the warning, press anywhere on the screen.  

You can find the full battery specifications here.


When the battery is installed in the Performance Box Touch, it will charge while the unit is being powered via a power source. You can also charge it while it is removed from the unit by using the supplied USB cable (USB2-007241). Note that the USB port on the battery is located above the Power button.

The battery needs approximately 3.5 hours to charge. To shorten the charging time, we recommended that you charge the battery from a mains power source while it is disconnected from the Performance Box Touch.

If you are experiencing issues when charging the battery, take a look at our troubleshooting page.

Auto Power-Off

When Performance Box Touch is 'idle' (tracking zero satellites, not logging and has no screen interactions for 5 consecutive minutes), it will power off to preserve the battery.

Before it powers off, it will display a warning screen. If you do not want it to power off, you can cancel the process by pressing anywhere on the screen within the 10 second time limit.

Using Gloves with Performance Box Touch

Just like modern mobile phones and tablets, Performance Box Touch is operated using a capacitive touch screen display. However, this does mean that if you are wearing gloves, they will need to be capacitive touch compatible to allow for interaction with the touch screen.

There are many types of capacitive touch compatible gloves available for purchase. If you are unsure which gloves you need, please do not hesitate to contact Racelogic.

Satellite Reception

Performance Box Touch has an internal patch antenna. This means that, in many circumstances, the unit does not require an external antenna if it has a clear view of the sky without any interference (e.g. roof bars, athermic windscreen, windscreen wipers). However, if you are struggling to maintain a stable satellite lock (indicated by a flashing red satellite icon), you can use an external antenna (RLACS284). VBOX Touch No Sats.png
The first time you use the unit, it may take 10 to 15 minutes to acquire satellites fully. After this, it will usually only take 1 to 2 minutes to acquire satellites.

External Antenna (If Required)

The placement of the GNSS antenna is crucial to the quality of the data recorded by Performance Box Touch. Any metal close to a GNSS antenna can unpredictably disturb the signal due to interference from reflections of weak GNSS signals.

For best results, use the antenna in the centre of a metal roof at least 5 cm away from any roof bars or radio antennas. Do not mount the antenna close to the edge of the roof as reflections from the ground may interfere with the signals. Avoid the edges as reflections from the A-pillars will cause problems.

Mount the antenna as high up as possible and keep it above any roll bars. Pieces of metal close to and above an antenna will badly disrupt the GNSS signal. 

If the vehicle you are using does not have a metal roof, you need to place the GNSS antenna on a flat piece of metal at least 10 cm in diameter. If this is not possible, you can use copper or aluminium foil to create a shaped ground plane underneath the antenna. For example, on a fibreglass roof, mount the antenna on top of the roof, and place some adhesive-backed metal foil underneath, on the inside of the roof.



Acquiring Satellite Lock

Tall buildings or trees can block GNSS signals, causing a reduction in the number and quality of satellites being tracked. The reduced number of satellites can lead to inaccurate position measurements and a noisy velocity signal.
GNSS works best in open areas. Avoid tree-lined roads.

GPS Coldstart

If Performance Box Touch is struggling to acquire a satellite lock, you may need to perform a GPS coldstart. This may be necessary when the unit hasn’t been used for several days or has moved location significantly since it was last used.

To perform a coldstart, press the COLDSTART button in the Diagnostics Settings menu.

Performance Box Settings Diagnostics v1.5 (v2).png
When you press the button, the unit will make an audible sound and you will see a ‘PLEASE WAIT’ message counting down from 3. Until the satellite lock has been acquired, the number of satellites will be displayed as '00' and the GPS status will show ‘SEARCHING FOR SATELLITES’. It will take approximately 25 to 30 seconds for the unit to reacquire the satellite lock.


You can access the Settings menu on Performance Box Touch by selecting the Settings button on the bottom left of the screen when in a mode. You will see a Select Settings Screen with 4 Settings options: Mode settingsGeneral SettingsTime settings and Diagnostic settings.
